Overview
- Group chats support up to 20 participants and can be started from the people icon with invite links for quick onboarding.
- Access in the pilot spans Free, Go, Plus and Pro plans across web and mobile, with conversations listed in a new sidebar section.
- GPT-5.1 is tuned for group dynamics, choosing when to respond, reacting with emojis and using profile photos as references.
- OpenAI says group conversations do not use or store personal memories, and only AI-generated replies count against the invoker’s usage quota.
- If participants under 18 are present, the system automatically reduces exposure to sensitive content, and members have profile, moderation and exit controls.
